左丘明与《左传》《国语》关系考论

《左传》作者是否为左丘明至今仍有争议 ,争议的主要原因是左丘明生活年代与孔子同时而《左传》却成书在公元前 4 0 3年之后。本文借助一些史料推理分析 ,认为左丘明当是《左传》的始撰写者 ,撰写内容传授给弟子 ,其弟子据自己亲眼所见对预言及某些内容按照左丘明的思维轨迹进行了调整增删 ,最后的定稿人至少活到了公元前 4 0 3年。关于左丘明与《国语》的关系 ,本文通过对写作过程的逻辑推理 ,认为编撰《国语》是撰写《左传》的必经步骤 ,但是左丘明编撰之《国语》今已不传了。     

苏联强军固国战略溯源

苏联的科技强国战略具有“军事科技优先”的鲜明特色 ,这种强军固国战略在其形成过程中深受列宁、斯大林的重大影响。苏联建国初期的严峻形势逼迫苏联着力发展国防建设 ,他们对先进武器的认同促成苏联的强军固国理念 ,军事科技的二战实效校验了苏联强军固国实践。     

Group Buying of Competing Retailers

Under group buying, quantity discounts are offered based on the buyers' aggregated purchasing quantity, instead of individual quantities. As the price decreases with the total quantity, buyers receive lower prices than they otherwise would be able to obtain individually. Previous studies on group buying focus on the benefit buyers receive in reduced acquisition costs or enhanced bargaining power. In this paper, we show that buyers can instead get hurt from such cooperation. Specifically, we consider a two‐level distribution channel with a single manufacturer and two retailers who compete for end customers. We show that, under linear demand curves, group buying is always preferable for symmetric (i.e., identical) retailers. For asymmetric retailers (i.e., differing in market base and/or efficiency), group buying is beneficial to the smaller (or less efficient) player. However, it can be detrimental to the larger (or more efficient) one. Despite the lower wholesale price under group buying, the manufacturer can receive a higher revenue. Interestingly, group buying is more likely to form when retailers are competitive in different dimensions. These insights are shown to be robust under general nonlinear demand curves, except for constant elastic demand with low demand elasticity.     

The Fisher Transform of the Pearson Product Moment Correlation Coefficient and Its Square: Cumulants,Moments, and Applications

This paper extends results on the distribution of the Fisher transform of the correlation coefficient (Fisher, 1921 Fisher , R. A. ( 1921 ). On the “probable error” of a coefficient of correlation deduced from a small sample . Metron 1 : 1 – 32 . [Google Scholar]). Approaches to obtain exact moments of the Fisher transform for both null and non-null correlations are presented. We extend the classic series expansion formulae of Hotelling (1953 Hotelling , H. ( 1953 ). New light on the correlation coefficient and its transforms . Journal of the Royal Statistical Society, Ser. B 15 : 192 – 232 . [Google Scholar]) for the moments of the Fisher transform. These results are considered in the context of quadratic functions of the Fisher transform. Some applications of these results are discussed in the context of correlational hypothesis tests and confidence intervals, and a Monte Carlo experiment is used to demonstrate how application of these results impact the small sample performance of select tests on correlations.     

Waiting to Inhale: The Demographics of Toxic Air Release Facilities in 21st‐Century California*

Objectives. We examine the spatial distribution of toxic air releases and residential demographics in California using 2000 Census data and coeval information from the Federal Toxic Release Inventory for evidence of disproportionate exposure. Methods. We use spatial analysis using GIS, and multivariate regression analysis, including ordered and multinomial logit regressions, in our study. Results. Analytical results suggest a pattern of disproportionate exposure based on race, with the disparity most severe for Latinos, which holds in a series of multivariate regressions, including attempts to test for varying levels of pollution risk and to control for spatial dependence. Conclusions. The study corroborates earlier research focused in the Los Angeles area, and suggests that recent concerns about environmental inequities affecting Latinos in California may be well founded.
